Gilles Peskine 5a7702e76d Fix some C function documentation in the test framework
The primary goal of this commit is to fix various comments where
`clang -Wdocumentation` identified a discrepancy between the actual
function parameters and the documented parameters. The discrepancies
were due to copypasta, formatting issues or documentation that had
diverged from the implementation.

Gilles Peskine c86a16548c Don't use STATIC_ASSERT_EXPR on non-GCC-compatible compilers
ARRAY_LENGTH has a portable but unsafe implementation, and a
non-portable implementation that causes a compile-time error if the
macro is accidentally used on a pointer.

The safety check was only implemented for __GCC__-defining compilers,
but the part that triggered the compile-time error was always used. It
turns out that this part triggers a build warning with MSVC (at least
with some versions: observed with Visual Studio 2013).
```
C:\builds\workspace\mbed-tls-pr-head_PR-4141-head\src\tests\src\psa_crypto_helpers.c(52): error C2220: warning treated as error - no 'object' file generated [C:\builds\workspace\mbed-tls-pr-head_PR-4141-head\src\mbedtls_test.vcxproj]
C:\builds\workspace\mbed-tls-pr-head_PR-4141-head\src\tests\src\psa_crypto_helpers.c(52): warning C4116: unnamed type definition in parentheses [C:\builds\workspace\mbed-tls-pr-head_PR-4141-head\src\mbedtls_test.vcxproj]
```

Since a compile-time error is never triggered when the compile-time
check for the argument type is not implemented, just use the unsafe
macro directly when there's no safety check.

Gilles Peskine 65048ad648 Destroy recorded persistent keys in PSA_DONE()
This ensures that test cases won't leave persistent files behind even
on failure, provided they use TEST_USES_KEY_ID(). Test cases that
don't use this macro are unaffected.

Tests that use PSA_DONE() midway and expect persistent keys to survive
must use PSA_SESSION_DONE() instead.

diverged. Re-align the copy in preparation from moving the code to a

Gilles Peskine 2385f71abd Fix and simplify test assertions
mbedtls_test_fail does not copy the failure explanation string, so
passing a string on the stack doesn't work. This fixes a garbage
message that would appear if a test triggered a non-implemented code
path.

More generally, just use TEST_ASSERT instead of explicitly calling
mbedtls_test_fail, since we aren't playing any tricks with the error
location.

Gilles Peskine cc9db30851 exported_key_sanity_check: make checks slightly more systematic
Shuffle the logic in mbedtls_test_psa_exported_key_sanity_check()
somewhat. The resulting behavior changes are:

* Always check the exported length against PSA_EXPORT_KEY_OUTPUT_SIZE,
  even for unstructured key types.
* Always complain if a key type is not explicitly covered, not just
  for public keys.

Gilles Peskine b15832160b Make entropy double-free work
Although the library documentation does not guarantee that calling
mbedtls_entropy_free() twice works, it's a plausible assumption and it's
natural to write code that frees an object twice. While this is uncommon for
an entropy context, which is usually a global variable, it came up in our
own unit tests (random_twice tests in test_suite_random).

Announce this in the same changelog entry as for RSA because it's the same
bug in the two modules.

Gilles Peskine eb94059edd Fix mutex double-free in RSA
When MBEDTLS_THREADING_C is enabled, RSA code protects the use of the
key with a mutex. mbedtls_rsa_free() frees this mutex by calling
mbedtls_mutex_free(). This does not match the usage of
mbedtls_mutex_free(), which in general can only be done once.
